<?PHP
$knownSinner = mysql_query("SELECT * FROM `idiotlist` WHERE `username` = 'knownSinner'");
if(mysql_num_rows($knownSinner) == 0) {
    print "You are only lying to yourself...";
} elseif(mysql_num_rows($knownSinner) > 0) {
    print "Thats what i thought.";
}
?>

or

<?PHP
$knownSinner = mysql_query("SELECT * FROM `idiotlist` WHERE `username` = 'knownSinner'");
$n = mysql_num_rows($knownSinner);
if($n == 0) {
    print "You are only lying to yourself...";
} elseif($n > 0) {
    print "Thats what i thought.";
}
?>

Wait.. So your saying my mysql could be better?

Im very confused..

Doing if(mysql_num_rows($knownSinner)){ is a longer way of counting the rows...

the second one you have done almost exactly the same except added if($n >0).

There was no need for an elseif as else works just fine.

whats the point though in using another if statement when you can use the one your alread y using?

[CJ-real]

I don't see the point in brackets either... unless you are doing functions as in, or headers etc....

function whatever($echo)


ohhhh http://www.php.net/quickref.php

[--ss--]

<?php
  echo("I actually think it's much neater and clearer by having it with brackets surrounding the speech marks but that's just my personal opinion.");
?>

[Protege]

I agree to that

Your the one that did lol

I had else{ and you put elseif{

if($x == 0) {
// error
} elseif($x > 0) {
//succeed
} else {
// error
}

apposed to

if($x == 0) {
// fail
} else {
if($x > 0) {
// succeed
} else {
// fail
}
}

if($x == 0) {
// error
} elseif($x > 0) {
//succeed
} else {
// error
}

apposed to

if($x == 0) {
// fail
} else {
if($x > 0) {
// succeed
} else {
// fail
}
}

Or you could just do
if( $x >= 1 )
{
//success
}
else
{
//fail
}
